canon rumors FORUM

Standard

I dug through the forums here, and I didn't see a dedicated thread (there was some good info in the 12-24mm thread tho).

You did not find anything, because Rokinon does not make lenses, they rebrand other makes. Search for Samyang.

That's absolutely right. Samyang lenses are also sold under other brand names such as Rokinon, Bower, Pro-Optic and Walimex Pro. Interestingly, the exact same lens cost less if you were to buy it under these other names instead of Samyang. For instance, the ultra wide angle Samyang 14mm for the Canon mount under the Pro-Optic label cost $359 while under Bower costs $384 at Amazon. At B&H, under Rokinon it costs $359, under Bower $384 and Samyang $399.

I was looking for a very wide angle lens and read so many excellent comments and reviews for this that for the price it was worth taking a chance - and I'm glad I did.The first thing you need to do is download lens correction software - I got PTlens - this corrects the slightly odd distortion (the main negative point against the Samyang 14mm).The build quality - other than the lens cap seems very high for such a price - very smooth distance ring.You will need to do a few quick tests with the infinity and distance markings - I have it set at the infinity mark - and at around f8 and above its very sharp.I've found that rather than it being a lens to get 'everything in' it works best when you get very close up to something (in a landscape like a building etc)- the images are very dynamic.The main problem I have is being able to focus on small objects like for example a wine glass on a table - it takes a lot of practise.I've done a load of shots at f2.8 hand held at night at iso 3200 on a 5d3 on city street images and and was pleased with the results, I would absolutely recommend this lens - it takes a little work at first but for the price - its around £1500 cheaper than the Canon - its worth the chance (even though Ken Rockwell'sreview was not good - the only bad one i've read though).

Personally, I much preferred the used Canon 15mm fisheye to the 14mm Samyang I bought and returned.Here are images from the same point using each. Note that the fisheye shows a wider view than the Samyang and is not badly distorted on the left side.I haven't tried the defishing software with the fisheye image.Canon 15mm FE

Great lens, especially for the price. Indeed, it seems to be as good as the Canon 14mm 2.8 II and better than version I. I process my photos in Lightroom and the profile I downloaded through the Profile downloader is good, but I found a better one I have yet to install manually. The existing profile corrects the wavy distortion fine and also the vignetting. There is no chromatic aberation to speak of. The profle is efficient, in that it crops very little of the image.Here are a couple of photos. The first is on a 5D MkII 30 seconds at f2.8 at ISO 3200.The second is at 1/40 at f8 ISO 100.Cheers

I was recently at the Houston Arcade Expo this past weekend....and a guy there I met shooting it, and we got to talking.He had the Bower version of it...so, we swapped lens for awhile walking around, I tried out the 14mm....and I think I either let him work with my Canon 17-35mm or it was my Canon 85mm 1.4....

Anyway, I was really liking what I was getting with the Bower 14mm on my 5D3...I've not had a chance to see them off the camera yet, but when I can get to it...I'll see if I can post a couple that might have come out good with it.

I'm definitely wanting to get one...I'd originally been looking at saving for the Canon 14mm...but I think I might get one of these Bower/Samyan/Name of the month.......and start playing with it.

I liked the rectilinear look of it...having it not be fisheye.

I will likely get a really wide fish eye some day...but I think some form of 16mm will do me for now...

Just keep in mind that software that corrects distortion lowers the resolution. At least this is what I have seen reported even for the superb Zeiss 21mm f/2.8 (which by the way has a mustache distortion).
